  As described above, according to the display device 2 according to the present embodiment, the operation of moving the display region 13 arranged on any one of the four sides of the screen 11 to any one of the four sides can be simplified.

  A first modification and a second modification of this embodiment will be described. In the first modification, the display area 13 is moved according to the rotation angle of the gesture indicating one rotation. Such gestures include a third rotation gesture and a mouse gesture for drawing a circle with the mouse pointer P on the screen 11. The third rotation gesture will be described as an example. As described above, the third rotation gesture is a single touch, and is a gesture for drawing a circle by moving the fingertip of one finger on the screen 11.

  In the first modification, an angle detection unit 507 shown in FIG. 2 is used. The angle detection unit 507 detects the rotation angle of the movement indicated by the third rotation gesture using the touch position on the screen 11 detected by the touch panel display unit 403. Specifically, when the fingertip of one finger is touched on the screen 11 and an operation of drawing a circle on the screen 11 is performed, the angle detection unit 507 calculates the center (rotation center) of the circle, and the screen 11, the rotation angle from the position (start point) where the touch is started is calculated.

  Referring to FIG. 3, when the third rotation gesture is counterclockwise, based on the lower side (first side) of screen 11, the lower side of screen 11 and the right side (second side of screen 11) according to the rotation direction. ), The upper side (third side) of the screen 11, and the left side (fourth side) of the screen 11 are arranged.

  On the other hand, when the third rotation gesture is clockwise, based on the lower side (first side) of the screen 11, the lower side of the screen 11 and the left side (second side) of the screen 11 according to the rotation direction. The upper side (third side) of the screen 11 and the right side (fourth side) of the screen 11 are arranged.

  One rotation indicated by the third rotation gesture is a first angle range of 0 ° to less than θ1 (eg, 0 ° to less than 45), and a second angle of θ1 to less than θ2 (eg, 45 ° to less than 135 °). A third angle range of θ2 or more and less than θ3 (for example, 135 degrees or more and less than 225 degrees), a fourth angle range of θ3 or more and less than θ4 (for example, 225 degrees or more and less than 315 degrees), θ4 or more and 360 degrees Divide into a fifth angle range of less than (for example, not less than 315 degrees and less than 360 degrees).

  When the gesture determination unit 505 determines that a third counterclockwise rotation gesture has been made in a state where the display area 13 is arranged on the lower side of the screen 11 as illustrated in FIG. 3, the angle detection unit 507 detects the rotation angle of the movement indicated by the gesture.

  The display control unit 503 moves the display area 13 from the lower side of the screen 11 to the right side of the screen 11 when reaching the second angle range without moving the display area 13 in the case of the first angle range. Are arranged on the right side of the screen 11 (FIG. 5), and when the third angle range is reached, the display area 13 is moved from the right side of the screen 11 to the upper side of the screen 11 and arranged on the upper side of the screen 11 When the fourth angle range is reached, the display area 13 is moved from the upper side of the screen 11 to the left side of the screen 11 and arranged on the left side of the screen 11 (FIG. 7). When the angle range is reached, the display area 13 is moved from the left side of the screen 11 to the lower side of the screen 11 and arranged on the lower side of the screen 11 (FIG. 3).

  According to the first modification, the display area 13 arranged on any one of the four sides of the screen 11 can be moved to any one of the four sides by a gesture indicating one rotation.

  Next, a second modification will be described. In the second modification, there are a plurality of display areas, and any one of the display areas is selectively moved. FIG. 16 is a diagram illustrating a specific example of the screen 31 applied to the second modification. Among the constituent elements of the screen 31, the same constituent elements as those of the screen 11 shown in FIG.

  The screen 31 includes a display area 33 in addition to the display area 13. The display area 33 is disposed on the upper side of the screen 31 and has an elongated shape extending along the upper side. The display area 33 is an area where, for example, a menu bar is displayed. In the second modification, the screen 31 includes two display areas 13 and 33, but may be three or more.

  The gesture determination unit 505 illustrated in FIG. 2 uses a touch position on the screen 31 detected by the touch panel display unit 403 to rotate a gesture or a mouse on any of the two display regions 13 and 33. It is determined whether or not a gesture has been made. The display control unit 503 moves one of the four sides of the screen 31 by moving the display region in which the rotation gesture or the mouse gesture is performed among the two display regions 13 and 33 on the screen 31 according to the rotation direction indicated by the gesture. The remaining display area is not moved while being arranged on the side.

  The second modification will be described by taking the second rotation gesture as an example. As described above, in the second rotation gesture, the fingertip of one finger is not moved on the screen 31 (in other words, fixed), and the fingertip of the other finger is moved on the screen 31 to draw an arc. It is a gesture. The direction of rotation indicated by the second rotation gesture is clockwise, and the display area to be selected is the display area 33.
